AUTOMATC STORM-SASH LFTER.

Application led February 11, 1922'.l Serial No. 535,779.

T0 all whom lit may concern:

Be it known that I, ALEXANDER CHIsHoLM, a citizen of the .United States,residing at St. Cloud, in the county of Stearns and State of Minnesota,have invented certain new and useful lmprovements 1n Automatic Storm-Sash Lifters; and l do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in storm sashopeners, and has for its primary object the provision of means adaptedto` automatically open and close a.' storm sash by the opening andclosing of the sash of the window'to which the storm sash is applied andthereby obviate the necessity of a person having to open and close thestorm sash independently of the window sash as now customary, and alsosaid means forms an elfective lock for the storm Sash when the windowsash is locked.

Another object of this invention is the provision -of a storm sashlifter or opener of the above stated character which will be simple,durable and elficient, and which may be manufactured and sold at acomparatively low cost. l

lilith these and other objects will become more apparent as in view, as

- the description proceeds, the invention consists in certain novelfeatures of construction, comblnation and arrangement of parts as willbe hereinafter .more fully described and claimed.

For a complete understanding of my 1n- Yention, reference is to be hadto the followlng description and accompanylng drawings, in which: y

Figure 1 isv a sectional view illustrating an automatic storm sashlifter or opener constructed. in accordance with my invention,.

Figure 2 is a sectional View taken on the line 2-2 of Figure 1,

Figure 3 is a front a guide, i

igure 4 is a detail sectional view, 1llus 5o trating the stop formed bythe upper .end

elevation illustrating Figure 3, Figure of the guide, and taken on theline 4-4 of 5 is a detail nsectional view taken on the line 5-5 ofFigure 3, and

Figure G is a. detail sectional view illustratmg the connection betweenthe wlndow sash and the operating rod.

Referring in detail to the drawings, the

numeral 1 indicates a window frame of well known construction upper andlower a having the usual window sashes 2 and 3 that are mounted forsliding movement so that the windo-w may' be opened and closed asdesired. A storm sash et has its upper end secured while. its lower tothe window frame l by hinges 5,

end engages the sill 6 of the frame 1. rlf`he foregoing descriptionrelates to a 'well known window construction to which my invention isapplied, for the purpose of opening and closing the storm sash l by theopening and closing of the lower sash Bof the window. l

My invention comprises an actuating rod i 7 that has one end pivotally,adjustably .connected to the the lower sash removably and lower rail ofa channel iron bracket S, while the other end of said rod is angularlvbent to form a roller axle or journal .9

and on which is mounted a. roller 10 operable against a guide 11 securedto the storm 80 sash 4 or to one of the side rails of the latter. Theguide 11 comprises separablelates arranged at right angles to each otherand detachably connected by tongues 12 and one of said plates isprovided with 12 through which is secured to the storm -sash 'by likefasteners 14, and when it is guide 11 screws or a slot v the axle 9extends. vrlhe desired to remove the device from the storm sash, the rod7 is unfastened from the 90 11a having the slot 1Q isV tilted to removethe tongues from the slots that are in the other., plate quently freeingthe .right anglesto the-storm sash with the rod 11, conseplate 11a whichis at 7 so that said parts may be stored away iny dependently of ingrod-.adjacent to the axle 16 which is angularly bent to with an arm forma Journal the storm sash. rThe actuat- 9 is provided for a roller 17 andthe latter roe is spaced. slightly Ifrom the roller 10 and is adapted,during the initial movementof the actuating rod, to come in engagementwith an inclined guide 18 secured to the window frame 1 for the purposeof `causing a'l direct outward pressure to be exerted on the storm sashon the initial movement of the lower sash 3 into an open position andthis outward pressure or force is for the purpose of releasing the stormsash in case the latter is sligthl -wedged onstuck in the window frame.uring the final movement of the lower sash 3 into an open position, theactuating rod assumes a horizontal-position, as

shown in dotted lines in' Figure 1, with the roller 17 engaging the stop15 formed by the slot 12 toobviate any possible chanceoff the rollersupporting'end of the 'actuating rod from sliding downwardly inthe slot12 of the guide when the actuating rodis disposed horizontally or inease'the pivoted end of the actuating rod is slightly higher than' theroller end, .consequently obviatin any possibility of the storm sashfalling into aclosed position when the lower-sash3 is in afully openedposition. The roller 17 also rides against the outer edge of said lastplate 11a during the upward and. outward movement of the rod. l

With the parts in the position shown in full lines by Figure' 1, itisimpossible to swing the storm sash 4 outwardly `or into an openpositlon, owing to the actuating ro'd 7 being in engagement with a guideroller 19 journaled to the frame 1, and lalso thisguide roller isadapted to bring about an e'ective closing of the storm sash when thelower Y' wlndow sash 3 is in .a fully closed position.v

'A person desiring to y v'entilate the room ralses the lower sash 3 anupward direc# sash 4 to swing outwardly of the window frame, 4owing tothe actuating rod 7 being plvoted to the lowersash 3 and the roller 10and 17 engaging the guide 11 and also the roller 17 engaging the guide18. Sliding movement of the actuating rod 7 in respect to the guide 11is limited bythe axle 9 of the roller 10 coming incontactl with'theupper end of the slot 12, therebyI causing an outwardly forcing actionagainst the sash 4, and as the lower sash 3 reaches its fully'openposition, the actuating rod assumes a horizontal position with both ofthe rollers in engagement with the guide thereby forming an effectivesupport for the storm sash 4 when in an open position. Also, the roller17 being in enga ement with vthe stop 15 obviates any possi ility of theroller end of theactuating rod sliding downwardly in the slot \12 andpermitting the storm' sash to i y move towards a closedposition. It istobe understood that in actual practice, a pair of these devices will beapplied to the side rails of a storm sash and also to the side rails ofthe lower sash so as to provide an effective opening means to eachv sideof the storm sash as well as forming an effective support for lcach side'of the storm sash when in an open parts may be made without departingfrom the spirit and scope of the invention'y as claimed.

Having thus described my invention, what l. clann is: the rounded end ofthe plate 11n which has f 1. 'The combination with a window framehavinga slidable sash and a storm sash l hinged thereto, of Va guidesecuredto the storm sash, an actuating rod pivoted to the slidable sash,a 'roller carried by said actuatf.

ing rod and engaging the ide, 'and means on the guide to be engage bythe roller. to

prevent the movement ofthe actuating rod in one direction when the stormsash is open. 2. The combination with a window sash and la storm sash,of a' guide secured to the -4 engage the second guide during the earlstages of thevmovement of the' window-sas towards an open position tocause the actuating rodto apply a direct force against the storm sash inan outward direction,

3. The combination with 4a window sashy and-a storm sash, ofan actuatingrod pivoted' to the stornA sash, an inclined guide located y p betweenthe sashes, and a roller carried-by tlon and this movement causes vthestorm' the actuating rod to engage said inclined en aging the guidesduring the early stage ofgthe movement of the rod and a sto'pon theguide tobe engaged by the second lroller to preventl the rod fromsliding downwardly with respect' to the4 first guide "when thesashes'are in opened position.

5. A storm, sash operating mechanism comprising a guide adapted l'tobesecured 'i to a storm sash, said guide' having a'longi' ltudinal slot,la rod adapted to be plvotally connected to`a window sash, a secondgulcle adapted to be secured to a window frame in f an inclinedposition, a roller carried by saidl rod at its free end and adapted tomove in.

s to be attached.

1n testimony whereof I a'x my signature in presence of two witnesses.
